IMPROVEMENT m JOURNAL-BOXES.

Specification forming part of Letters Patent No. 183,776, dated December10, 1872.

' To all whom it may concern:

Be it known that I, J. HENRYHAYWARD,

of the city, county, and State of New York,

have made certain Improvements in the Method of Constructing andManufacturing J ournal-Boxes for railroad, marine, and stationarymachinery, of which the following is a specification:

Nature and Objects of thelncention Are to decrease the friction-surfaceof the journal-bearingupon the journal without weakenin g or disturbingthe relative condition of the styles at present in use; that by thusremetal (case-hardened) or steel may be used in lieu of cast metal toinsure strength and durability, and at the same time supply a meanswhereby the journal-bearing so improved may be manufactured morerapidly, in duplicate, and at a greatly reduced amount of labor andcost.

Description of the Acconwanying Drawing.

Figure No. 1 is an end elevation of the jour nal plates. Fig. No. 2shows the plates in combination, also journal-bearing surface. Fig. 3 isa plan of the. upper side or oil-cup portion of the same. Figs. Nos-4and 5 show another Figs. Nos. 6

General Description.

Figs. Nos. 1, 2, 3 are three views of the same journal-box.

A are plates of rolled, cast, or forged metal, of any desired kind,quality, or thickness, cut into the requisite form by means of dies andpunches operated by pressure, each'plate consequently being an exactduplicate of theother so as not even requiring retouching by a file.Each j ournal-box, as represented in Figs. 1, 2, 3, is composed of eightplates, A A, (more or less,) to wit: three right and three left recessed platesfalso two outside plates, as shown in Fig. No. 2. Theseplates are firmly bolted or keyed, or otherwise held securely togetherin such a manner as to be, for all ordinary purposes, one piece, asshown, by bolts B B B. The object of cutting the plates of this boxright and left is that where the friction and heating surface is reducedjust one-half, and the lubricating-surface increased in just proportion,there will be at the same time no con traction of the journal-bearingsurface, while the wear upon the journalor axle will be properlydistributed the same as though the bearing-surface was solid, as in theold style.

Fig. No. 3 is a viewof the top side of the box, which shows that eachplate A is cut to the full height and length of the box, for the purposeof insuring increased strength, it required, the intermediate plates A AA A be ing cut at angles or arched inward so'as to form recesses D D D Dfor the deposit of oil, which passes freely down throu h the drip holesE E E E.

As will be seen, the drip-holes are, in all cases, put in the recessedside of the plate, for by this means the orifice is at all times abovethe friction and heating surface of the axle, and is not, therefore,liable to become filled or gummed up, as must always happen where theorifice comes directly in contact with the axle.

As will be seen in Figs. 6 and '4', the oil may be conveyed to the axleby means of any suit able material to absorb it from the oil-cup, as atF, Figs. 6 and 7. It may also be found advantageous to fill the recessesformed by the alternate plates with suitable packing, especially thosein the bottom half of the journalbox, so as to retain and keep theoilinsuspension after it has passed down from the top. Also, when theplates are cut as in Figs. 6 and 7, the top and bottom half of the boxesare to be of a right and left alternate bearing'surface so as toequalize the wear on the axle.

This combination of plates, so cut and secured together, constitutes theelementary form of my invention, which is susceptible of nunierousmodifications, as exemplified in Figs. 4, 5, 6, 7, each and all being insubstance and efl'ect the same; and although the permanent design of myinvention in thus constructing the series of plates is for the purposeset forth,

still the same principle of decrease of friction and heating surfaces,without contraction of bearing-surface, with enlargedlubricating-surface, may be etfected in the cast orsolid jour-. nal-boxnew used.

I claim as my invention 1. The construction of journal-bearings of acombination of plates, substantially as and for the purposes herein setforth.

2. The plates A A, cut so as to form recesses in the bearing-surfaces ofjournal-boxes, substantially as shown in Fig. 4, for the purpose setforth.

3. A journal-boxconstructed with alternating bearing-surfaces andrecesses, in the manner described, and said recesses filled withsuitable packing to retain the lubricant, as set forth.

4. A journal-box constructed with alternating bearing-surfaces andrecesses D, as described, and provided with drip-holes E, located insaid recesses, as set forth.
